messed up by grain

[woundedbear]

i know i have read something about this on this forum but i cant find it and i must not be typing the right words in my search options
i drilled my axel holes last night with the block and when i checked to make sure everything worked correctly the one wheel didnt migrate out
when i check the cant it is almost straight and it seems to follow the grain of wood

is this a common problem or did i just screw up in drilling the hole or is the bit i am using a problem

i checked the grain patterns on the other blocks that i have and they run more vertical so i hope that wont be an issue again

Do you have a real sharp drill bit..if you dont it will walk

And the pine blocks in the cub kits are horrible. Sugar pine or something similar with less grain, and its just a bit lighter.

I chuck the bit up high in the drill press, this seems to help it not walk, I also look on the block at grain to dill the rears in a grain free spot. I do mess a lot of blocks up. I had a breakthrough though. On the DD4H dvd when he tells you how to test the wheels in the block before proceeding, he mentions to use good wheels and axles. I was not for a long time, when I prepped a set just for tuning it was amazing how quickly the wheels migrate, I wish I could get some of the old discarded bodies back out of the wood stove.

this was a sugar pine block. so i am disapointed i ruined it

i would go to you local lumber yard and buy some pine to practice on..then when you drill few good ones use the sugar pine

Try Basswood and go really, really slow when drilling the holes also...

Crank up the drill speed too, less chance to wander.

I believe what is being said here is to advance the drill bit slowly into the wood as you drill. Keep the drill speed high though.

And plunge the drill press up and down a lot. Especially when you first touch the wood with the drill bit.

Are you saying you want him to stroke the quill?

I think the point is to WALK down the hill and get em all, as opposed to RUN down the hill and get just one...lol! /images/boards/smilies/redface.gif

Yes, and move his feed lever up and down too.

Take it from a man who does a lot of plunging.
